Af-N @RG PAPER-STOCK REGULATOR.

To all whom t may concern: n

Be it known that I, LEMUEL B. DECKER, a citizen of the United States,residing .at Kenogami, Province ,of Quebec, Canada, have inventedcertain new and useful lmprovements in Paper-Stock Regulators;and I dohereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. Y

The present invention relates to paper stock regulators and moreparticularly to a contrivance for securing the "consistency ofgroundwood and sulphite stock used in the manufacture of paper, thisconstituting one of the important .objects of the invention.

Another object of the same is to provide a device whereby the percentageand. mixture of the paper stock may be adequately regulated andcontrolled, according to requirements, as well as the consistency ofsame.

A further object of the invention is in the provision of an apparatusthat does away with all beaters, jordans, beater tanks and jordan tanks,and` all power and equipment needed to runsame.

Another object of the same invention is to set forth a contrivance whosemain function is to produce. a continuous mixture of groundwood andsulphite at a regularly dened consistencyv and percentage,thereby-increasing the production and eiiiciency of the paper machine.

With the above and other objects in View which may appear as inherentlyrelated with the nature and scope of the present inven- `tion, referenceis now to be had, for the purpose of disclosing same, to the hereuntovannexed drawings forming an integral part of the specification, and,wherein the various parts being designated by numerals are referred tothroughout the description by the .same corresponding characters.

Of the above referred to drawings Figure 1 is a side elevation of theapparatus embodying the present invention;

Figure 2 is also a side elevation, enlarged, of a part of theinventionshowing its connection with the baie mixer;

Figure 3 is a sectlon in elevationof thei water tank `and automaticallyoperated Valve;

peripheral capacity, whereby the overflow of stock may be removed.

A gate 5 is formed in said recipients 1 and 3, and, has an adjustablepanel 6 slidably mounted in connection with same for the purpose ofcontrolling the size of the opening through which the stock from therecipient 1 is caused to be discharged on and through a hinged trough 7.r1`his trough member has one of its ends pivotally mounted on a knifeedge 8, while the opposite end of same is held in space by means of adrawbar 9 having its lower end iexibly secured to said trough, as shownat 10, and, its upper end resting, by means of a nut 11, on a scale beam12. With the nut 11, being in threaded engagement with the upper end ofsaid draw-bar, the slope of the trough 7 may be adjusted according torequirements.

The said scale beam 12 is supported by a frame structure 13 which alsosupports the' pivotable end of said trough, and, is fulcrumed on knifeedges 14 suitably secured to the upper portion of said ,frame structure13. One end of said scale beam is freely adjusted in a slot formed bythe meeting in space relation of the two extremities of the structuralframe members 15 secured one end'to the main structural framing 13. Alongitudinal slot 16 formed in the two parallelly meeting branches ofsaid members 15, engages an adjustable bolt and nut 17, for the purposeof limiting in an adjustable manner the upward -motion of the scale beam12. t c

A movable weight 18, slidably mounted on the scale beam 12, between theknife edges 14 and the structural frame members 15, provides for themeans of regulating, as desired, the weight of the stock materialadapted to flow by gravity down through the trough 7.

To the outer free end of the scale beam 12, is secured a chain 19, Whoseother end is operably connected to the power arm of a lever 2O fulcrumedat point 21 which is formed with a Water tank 22. wherein the quantityof water admitted, through pipe 23, is automatically regulated by a ballvalve 24. Thereby, when the Water Within said tank has attained apredetermined altitudeor level,'t he ball member 25 of said valveactuates, through a lever 26, the closing of said valve andautomatically cuts olf the supply of water into said tank.

Suspended from the extremity of the Weight arm of the lever 20, is avalve 27, Whose seat 28 is located on the inside bottom of said Watertank 22. Thisvalve is preferably of hollow cylindrical form, and whenclosed, as shown in Figure 3, completely recovers the perforated end 29of the water pipe 3() which projects on the inside of said Water tank.This Water pipe 30 leads from the Water box 22 to the inlet stock pipe 2or into the stuff box 1'.

Operatively, when the stock from box 1 is heavy coming through gate 5 onto the Weighin trough 7 beyond a certain required limit, the saidtrough, through the draw-bar 9, causes the scale beam to drop down,simultaneously causing the opening of valve 27, when Water, from thetank 22,l

rushing through the perforations 31 formed with the end 29 of pipe 30,immediately leads its Way through said pipe 30 into the stuff box 1. Thepulp being thereby thinned, the load on the Weighing trough 7 issubsequently lightened, when the scale beam 12 thereby caused to resumean upvvard motion, the valve 27 is shifted back tight upon its seat 31,and, the Water supply from the tank to the stuff box is automaticallycut ofl'. i

In this wyay a uniform lconsistency of the paper stock is continuallyand automatically ensured and adapted to be regulated.

The stock on leaving the above described regulator apparatus enters abaiiie mixer 32, which 1s made up of a plurality of cantilever shelves33 disposedin space relation to each other and alternately secured tothe opposing vertical Walls of said battle mixer. Therefrom, thecombined sulphite and groundwood stock is lead` through conduit 34, tothe pump fan 35. thence to the distributing h ead 36, from Where same iscontrollably distributed to the paper machine chests through pipes 3738, 39 and 40.

The above described procedure is followed `both in the case ofgroundwood and sulphite.` In fact, Figure 1 of the drawings shows on theleft hand side of the sheetthe 65 apparatus, embodying the presentinvention,

used in connection 4`With groundwood, While, on the right hand side ofthe same sheet, substantially the same apparatus is applied withrelation to sulphite, the baille mixer 32 being disposed therebetween soas to receive the discharge from both.

In the accompanying drawings and foregoing description have been shown asimple and preferred form of the invention. It is however understoodthat no limitation is necessarily made to the precise structural detailstherein exhibited, but the right is hereby reserved to any changes,alterations or modifications to which recourse may be had that comeWithin the scope of the following claims Without departing from thespirit of the invention or sacrificing the efciency of the same.

Having thus fully described my invention, what I claim as new and desireto secure by Letters-Patent, is

l. An apparatus of the character herein described, comprising means forautomatically regulating the consistency and percentage of groundivoodand sulphite stock used in the manufacture of paper.
